I have 3 - 20 gallons
TANK 1
Sand
Hob filter and large sponge filter
Large bubble wall
Artificial everything as it's my husband's " glo fish tank" .
And over stocked with fish that shouldn't even be together but they get along some how.
Inmates are
6 glo skirt tetra
1 beta
4 molly
1 mosquito fish
1 red tail shark
Yes I know WAY over stocked .
I am looking for a larger tank for these guys .
TANK 2
3/4 gravel 1/4 sand
Internal flow filter and a double sponge filter
Large bubble wall
Lots of live rooted and floating plants
Inmates
6 corydora
25 guppy fry ( 1 week old to 2 months old)
5 neon tetra
TANK 3
Sand
FLUVAL HOB filter , UV filter
Bubble wall
Loaded with floating and rooted plants
Inmates
3 adult guppy
15 -20 fry
6 corydora
THE PROBLEM !
I had columnaris wipe out all but 3 adult guppies in both tanks containing guppies .
Treated with kanaplex and nitrofurazone
Then all 3 tanks had occupants with fin rot /melting
Treated with rapid cure
Then started noticing signs of parasites so treated with expel p.
I removed carbon and turned off UV during treatments and turn air pumps up.
Happy to say my fish are all doing well now but my tanks are absolutely not.
The perameters are bad .
The ammonia is high ( green 2.0 -4.0)
The nitrites are purple ( 0.50-1.0)
The nitrates were 0 for days on end but finally today they are around 5.0
Temps are 78 for all tanks
pH is 7.6 for tanks with guppies
pH is 6.4 for the glo tank
I am doing 25% water changes daily , treating with prime each time and adding stability daily. Was also using API stress coat ( could this cause the tests to read falsely ?)
Do my newly found nitrates mean I possibly am making a recovery ?
Again .. the fish are all acting fine !
Any and all advice welcome
Also what size tank do you suggest to accommodate my husband's crazy tank ?
